Polyether polyol yog cov khoom siv tshuaj tseem ceeb heev, siv dav hauv kev lag luam xws li luam ntawv thiab dyeing, papermaking, hluavtaws tawv, coatings, textiles, foam plastics thiab roj av kev loj hlob.Kev siv ntau tshaj plaws ntawm polyether polyol yog los tsim polyurethane (PU) ua npuas ncauj, thiab polyurethane yog siv dav hauv cov rooj tog zaum hauv tsev, khoom siv hluav taws xob, kev tsim kho, cov ntaub ntawv khau, khoom siv hauv tsev, tsheb thiab ntim khoom.Kev lag luam kho kom zoo nkauj dominates tag nrho cov kev xav tau ntawm kev lag luam, ua raws li kev lag luam kev tsim kho, thaum lub lag luam khoom siv hauv tsev thiab kev lag luam kev kub ceev yuav dhau los ua qhov tseem ceeb tshaj plaws kev loj hlob ncej rau yav tom ntej polyurethane xav tau.

1. Detergent lossis defoamer

L61, L64, F68 yog siv los tsim cov tshuaj detergents uas tsis muaj npuas thiab siab detergency;

L61, L81 yog siv los ua defoamer hauv papermaking lossis fermentation kev lag luam;

F68 yog siv los ua defoamer hauv cov ntshav ncig ntawm lub plawv-lub ntsws tshuab kom tsis txhob muaj cua nkag mus.

2. Excipients thiab emulsifiers

Polyethers muaj toxicity tsawg thiab feem ntau yog siv los ua tshuaj excipients thiab emulsifiers;lawv nquag siv hauv qhov ncauj, tshuaj tsuag qhov ntswg, qhov muag, pob ntseg tee thiab tshuaj zawv plaub hau.

3. Tus neeg saib dej ntub dej

Polyethers yog cov neeg ua haujlwm ntub dej zoo thiab tuaj yeem siv rau hauv cov kua qaub da dej rau dyeing ntawm cov ntaub, kev txhim kho duab thiab electroplating, siv F68 hauv cov suab thaj mills, ntau cov suab thaj tuaj yeem tau vim muaj dej permeability.

4. Antistatic tus neeg sawv cev

Polyethers yog cov tshuaj tiv thaiv zoo, thiab L44 tuaj yeem muab kev tiv thaiv electrostatic ntev rau cov hluavtaws fibers.

5. Dispersant

Polyethers yog siv los ua dispersants hauv emulsion txheej.F68 yog siv los ua emulsifier hauv vinyl acetate emulsion polymerization.L62 thiab L64 tuaj yeem siv ua tshuaj tua kab emulsifiers, coolants thiab lubricants hauv hlau txiav thiab sib tsoo.Siv los ua cov roj nplua nyeem thaum lub sij hawm roj hmab vulcanization.

6. Demulsifier

Polyether tuaj yeem siv los ua cov roj demulsifier, L64 thiab F68 tuaj yeem tiv thaiv kev tsim cov nplais nyuaj hauv cov kav dej, thiab tuaj yeem siv rau cov roj rov qab.

7. Papermaking pab

Polyether tuaj yeem siv los ua kev pabcuam papermaking, F68 tuaj yeem txhim kho zoo ntawm cov ntawv coated;nws kuj yog siv los ua ib qho kev pab yaug.

8. Kev npaj thiab kev thov

Polyether polyol series cov khoom siv feem ntau yog siv rau kev npaj ua npuas ncauj polyurethane ua npuas ncauj, uas yog dav siv hauv tub yees, tub yees, tub yees, tsheb tub yees, hluav taws xob rwb thaiv tsev, hluav taws xob rwb thaiv tsev thiab lwm yam.Cov khoom npaj muaj tsawg thermal conductivity thiab zoo seem stability, thiab kuj yog ib qho tseem ceeb raw khoom rau kev npaj ua ke polyether.Kev tsim cov polyether polyols

Hauv kev lag luam polyurethane, nws yog tsuas yog siv rau polyurethane ua npuas ncauj, thiab lub ntsiab ntau yam yog polyoxypropylene polyol thiab polytetrahydrofuran ether polyol.

Vinyl polymer grafted polyether polyol feem ntau hu ua "polymer polyol" (PolyetherPolyol), abbreviated li POP.Polymer polyol yog raws li cov polyether polyol (feem ntau yog cov mos mos ua npuas ncauj polyether triol, siab polyether), ntxiv acrylonitrile, styrene, methyl methacrylate, vinyl acetate, chlorine Ethylene thiab lwm yam vinyl monomers thiab cov pib yog tsim los ntawm radical graft polymerization degrees ntawm txog 10. thiab nyob rau hauv kev tiv thaiv nitrogen.POP yog ib qho organically sau polyether polyol siv rau kev npaj siab load bearing lossis siab modulus saj zawg zog thiab semi-rigid polyurethane ua npuas ncauj khoom.Ntu lossis tag nrho cov kev coj ua uas tau muaj dua tshiab yog siv hloov chaw dav dav thiab cov kev ua tau zoo-cov kabmob-cov kev ua tau zoo polyols, tab sis kuj tseem txuag cov khoom raw.Cov tsos mob feem ntau yog dawb los yog lub teeb milky daj, kuj hu ua dawb polyether.

Kev Tshaj Tawm: Cov kab lus tau hais los ntawm Lunan Polyurethane Cov Khoom Tshiab ntawm WeChat 10/2021 Tsuas yog rau kev sib txuas lus thiab kev kawm, tsis txhob ua lwm yam kev lag luam, tsis sawv cev rau lub tuam txhab cov kev xav thiab kev xav, yog tias koj xav tau rov luam dua, thov hu rau tus sau thawj, yog tias muaj kev ua txhaum cai, thov hu rau peb tam sim ntawd kom tshem tawm cov txheej txheem.
